Application filed April 6, 1893. Serial No. 469,367. (No model.)

To all whom it may concern: 7

Be it known that I, JOHN W. ROBERTS, a citizen of the United States, anda resident of Cleveland, county of Cuyal'roga, State of Ohio, haveinvented certain new and useful Improvements in Oan-Seaming Machines, ofwhich the following, with the accompanying drawings, is a specification.

The object of my invention is a machine which automatically bends thetin to form makes and solders the seam, and discharges the seamed canbody from the machine ready to have the ends of the can crimped upon thecylindrical body.

My invention consists in the construction and combination of the severalparts hereinafter described and defined in the claims.

In the drawings, Figure 1 is a side elevathe forming and clampingapparatus, the ad jacent parts of the 'm'achinefbeing broken away, andFig. 8 is a side elevation of the parts illustrated by Fig. 7.-, Fig. 9is a plan view of the segmental clamps.

mechanism, and the soldering mechanism. For the sake of clearness, eachof these mechanisms is separately described, and then their 1 jointoperation is explained. Carrying out this plan of deductive analysis inthe description, the claim resolves itself into four classes ofparagraphs: the first class being directed to the stock-feedingmechanism; the second class being directed to the forming and clampingmechanism; the third class being directed to the soldering mechanism;and the fourth class to the various combinations of the elementsentering into these various mechanisms.

' I will first describe the stock-feed mechanism. By reference to Figs.4, 5 and 6, the stockfeed table and mechanism connected there"- with areshown independently of the other mechanism entering into the completemachine. The driving power which connects this mechanism with the mainshaft (24) of the machine will be seen in Figs. 1, 2 and 3. 1, 1, is anopen rectangular frame which constitutes the main frame of the machine.In front of the main frame 1, 1, is a supporting frame forming what Iterm the table of the machine. This frame consists of the sills 2, 3,4and 5, with the outer tie 6. The rectangular frame 7 is formed at theback of theframe forming the table. At'each end of the table is fixedguide rods Sand 9, which are held in place by the brackets 8' and '8",and 9' and 9". Upon these guide rods is sleeved a bar 10, which hasmovement along the guide necting' links 12 and 12 are pivoted. In'thesleeved bar 10 are formed slots 10 longitudinally thereof. Upon thesleeved bar 10 are two stock-guides 13 and 13, which have lateraladjustment upon the sleeved bar 10, by means of bolts 14 and 14 whichpass through the slots 10 and are secured in place by the thumb-nuts 15and 15'. The inner sides of thestock-guides 13 and 13' are recessed, asseen at 16,- leaving lugs, 16', to form a rest for the sheet of tin A.The stock-guides 13 and 13 have lateral slots 13"" through which passthe'bolts 17, 17', which carry lugs 17", similar to the lug orprojection 16", to form a rest for the sheet of tin A. These bolts 17and 17 with the thumb-nuts 18 and 18, make the stock-guides adjustablelongitudinally. These stock-guides 13 and 13', being adj ustablelaterally and longitudinally as described, may be adapted to feedingsheets of tin of various sizes to form cans of various sizes. From theunder side of the sleeved bar project rods 19 and 19'. Upon these rodsare brackets 20 and 20, which have adjustment vertically upon the rods19 and19' by means of the set screws 21. Said brackets carrydischarge-rods 22 and 22, which are L-shaped, the foot of the L passingthrough bores in said brackets and being adjustable therein by means ofthe set screws 23 and 23'. By means of the vertical adjustment of thebrackets 20 and 20' upon the rods 19 and 19, and by the lateraladjustment of the dischargerods 22 and 22 in said brackets 20 and 20,said discharge-rods are capable of vertical and lateral adjustment toaccommodate them to the work of seaming cans of various sizes. Saidstock-feed mechanism is operated from the main shaft 2i through themutilated gear 25, gear 26, crank-wheels 27 and 27, and links 28 and 28.The rocking-bars 20 and 29 are pivoted to the door, as illustrated; andsaid rocking-bar 29, connecting link 28, and link 12, are pivotedtogether at 28"; and the rocking-bar 29, connecting link 28, and link12', are pivoted together at 28. It will be seen by reference to Fig. 3that the mutilated gear has two sets of cogs with rests between thesame, so that the stock-feed mechanism is thrown in carrying with it asheet of tin, A, when there is a slight rest to allow the sheet of tinAto be clamped,ashereinafterdescribed. The second series of cogs uponthe mutilated gear25 then comes into play and throws thesheet of tin inthe recesses formed in the stock-guide rods.

I have now described fully the feed mechanism. I will next describe theforming and clamping mechanism. A cylinder, 30, having a flange plate 31at its front end, is secured to that portion of the main frame marked1',

Said cylinder 1, by any suitable means. is grooved through on its underside through its whole length, forming what I, for convenience, term anopen split cylinder. \Vithin the rectangular main frame, 1, 1, above theopen split cylinder 30, is a frame 32, having central cross-pieces 33and 33, which cross-pieces have a central openingthrough them. AVertical shaft, 34, passes through the openings in the cross-pieces 33and 33', said cross-pieces forming a guide for the vertical rod 34. Atthe top of the main frame 1 is journaled a shaft which carries a cam 36.To the top of the vertical shaft 34 is fixed a rectangular open frame37, through which the shaft 35 passes soldering mechanism.

soldering iron. and 62', are pivoted to the floor.

laterally, and which incloses the cam 36, as illustrated. Within the topand bottom of said frame 37, are friction rollers 38 and 38 which engagesaid cam 36, as it rotates, to prevent wear and to lessen friction. Asthe shaft 35 rotates, it carries the cam 36 with it, thus reciprocatingthe vertical-bar 34 through the crosspieces 33 and 33, as and for thepurpose hereinafter stated. At the back of the main frame, at its top,there is also journaled a shaft 39, which is parallel with the shaft 35.Upon the shaft 39 there is fixed a mutilated gear 40, which meshes with.the pinion 41 that is fixed upon the shaft 35. Said shaft 39 is drivenby power through the upright shaft 42, bevel gear 43 fixed to the top ofthe shaft 42, and the bevel gear 44 that is fixed to the outer end ofthe shaft 39. Two segmental clamps, 45 and 45, are hinged at their innerends to the T-end 34. of the vertical reciprocating shaft34, asillustrated. A cfoss-bar, 17, passes laterally through the machine frameabove the segmental clamps t5 and 15', and has abore to allow thevertical shaft 31 to have an independent movement through it. Links 48and 18' are pivoted to the segmental clamps 15 and 45', as illustrated,and are connected pivotally with the cross-bar 17. The link 48 isprovided with a slot 49, near its upper end, through which the pin 50passes. Upon said link 48, below the bar 47, is fixed a ring 51. Aspring, 52, is interposed between the ring 51 and the bar 47. The bar 48is slightly longer than the bar 48', for the purpose hereinafter stated.The pin 50 passes through a round bore in the upper end of the link t8,and there is no longitudinal play of the link 48 upon the pin 50' asthere is with the link 48 upon the pin 50. Crank-wheels 53 and 53arefixed to the outer ends of the shaft 35, and have driving connections,51- and 54:, with the crossbar 47. These driving connections, 51 and 54,have longitudinal adjustment by means of turn buckles 55 and 55, withright and left threads at their opposite ends.

Having described the construction of the stock-feed mechanism and theforming and clamping mechanism, I will now describe the My solderingiron, 56, is substantially of the form illustrated by Figs. 16 and 17.It is provided with an inner chamber 57 and air openings 58 in the backend.

The front end of the soldering iron is solid. A pipe, 59, enters thechamber of the soldering iron, as illustrated. A flexible gas tube,

60, is connected with the pipe 59 that enters the chamber 57 of thesolderingiron 56. Said solderingiron is reciprocated through the opensplit cylinder 30, as hereinafter described.

lThe soldering iron 56, in its reciprocating movement, travels over aroller 61, that is ournaled upon the main frame 1, 1'. In the center ofsaid roller 61 is formed an annular V-groove 61, which serves as a guidefor the Two slotted rocking-bars, 62 A cross-bar,

63, adapted to slide upon the rods 64 and 64:,

carry a support 63'.which has abore through its top through which thepipe 59 passes. Said pipe 59 is adjustable through the support '63 bymeans of the set screw 63". Upon the ends of the cross-bar 63 are stgdsand 65 which pass through the slots 62" of the slotted rocking-bars 62and 62'. Thesupport 63' is adjustable vertically upon the slidingcrossbar 63 by means of a set screw 63". set screw, 63",passes through aslot in the usual way so well known to mechanicsand is not illustrated.The on terends of the rods 64 and 64' are supported from the outer edgeof the table ofv the machine by the drops 6' and 6". Upon the shaft 66there. is fixed a pinion 67, and upon the shaft 24 there is fixed amutilated gear 68 which is independent of the mutilated gear 25. Uponthe outer ends of the shaft 66 are carried crank-disks, 69 and 69', andlinks 70 and 70 connect said crank-disks 69 and 69 with the slottedrocking-bars 62 and 62'. through the pinion 67, shaft 66, crank-wheels69 and 69', links 70 and 70', and rocking-bars 62 and 62', reciprocatesthe sliding cross-bar 63 with its attached support 63', and thesoldering iron 56, and allows the soldering iron to have rest after eachrevolution. The solder used in my machine is in the form of wire, 71,and is'rolied upon spools 72, which are journaled in the standards 73and 73. The wire solder, 71, passes up between two rollers 74 and 74,and through a guide tube 75. A plan view of the solder-feed rolls isseen in Fig. 12. Said rolls are provided with I-grooves, 74", which areserrated to insure a biting into the solder to at all times insurefeeding. One of said rolls,'74, is carried in sliding-blocks 76, 7 6which are held in gibbed ways to allow movement of the roller 74.Springs 77 and" 77 hold the rollers together. The object of thisconstruction is to allow ayielding of one ofthe rollers that it willfeed regularly over the solder wire of uneven sizes. is fed by means ofthe mutilated gear 78, which is fixed upon the shaft 24, and meshes withthe pinion 79 that is fixed upon the shaft 80 that carries the feed-roll74. The teeth, 81,0f the mutilated gear 7 8, enter sockets 7 8, and areremovable, so that agreater or fewer number of teeth may be employed andthereby regulate the amount of solder fed with each revolution of themachine. 82 isa shaft to which the drive-pulley (not shown) is attached.The shaft 82 rotates the vertical shaft 42 through the bevel-gears 83and 84; and said shaft 82 rotates the main shaft 24 through thebevel-gears 85 and 86.

Having fully described separately the three different mechanisms thatenter into my machine, I willnow describe their joint operation. 'Thestock-guides 13 and 13' are adjusted laterally and longitudinally, asdescribed, to take the required size of sheet-tin A; and thedischarge-rods 22 and 22 are properly adjusted vertically andhorizontally so that in their travel they will pass close to the ThisThe mutilated gear 68,

The solder side of the open split cylinder 30. The open split cylinder30 and the segmental clamps 45 and 45 being of a required size to formthe cylindrical part of the can, the'drivers 54 and 54' are adjusted bymeans of the turnvbuckles 55 and 55 to give the segmental the main shaft24 is constantly rotated by the driving-shaft 82, as described, and theshaft 42, is constantly rotated from the shaft 82, as

described. The first series of cogs upon the mutilated gear 25 engagesthe gear 26 that is fixed upon the shaft 26, throwing the stockfeed in,and carrying the sheet of tin A in over the opensplit cylinder 30, andbelow the segmental clamps 45 and 45'. The stock-feed carrier is then atrest, as the cog-wheel 26' is in the shorter of the two spaces betweenthe two series of cogs of the mutilated gear 25. While the stock-feed isat rest with the sheet of tin over the open split cylinder 30, the firstseries of cogs upon the mutilated gear 40 engages the cog-wheel 41 thatis fixed upon the shaft 35,thus rotating the shaft 35 and carrying withit the cam 36, which cam 36 engages the lower frictionlroller 38 anddepresses the vertical shaft 34 down so that the T-end 34 of thevertical bar 34 (to which the segmental clamps 45 and 45' are hinged)firmly grasps the sheetof tin A along the longitudinal center of theopen split cylinder, at which instantthe mutilated gear 40 has so farturned as to leave the pinion 41 at rest between the series of teeth ofthe mutilated gear 40. The second series of teeth upon the mutilatedgear 25 then comes into engagement with,the gear 26' and rotatescrank-whee1s 27 and 27', thus withdrawing the stock-feed guides 13 and13 and the discharge-rods 22 and 22 clear of the open split cylinder 30.The second series of teeth upon the mutilated gear 40 then engage thepinion 41 and rotate the shaft 35,which, through the drivers 54 and 54,forces down the cross-bar 47, and through the links 48 and 48' closesthe segmental clamps 45 and 45 over the open split cylinder 30 with thesheet of tin A between the clamps and the open split cylinder. It wasstated in the description of this part of the mechanism that the link 48was a trifle longer than the link 48' and that it was slotted at itsupper end and provided with a spring. The purpose of,

link 48 allow a sufficient depression of the cross-bar 47 and loweringof the link 48' to close down the segmental clamp after the closing ofthe segmental clamp 45, upon the open split cylinder to grip the sheetof tin tightly on the right side of the split cylinder. While thesegmental clamps 45 and 45' are closed upon the open split cylinder withthe sheet of tin A clamped uponthe split cylinder as described, thesoldering mechanism of the machine comes into play. The on utilatedgear78 (having the movable teeth 81) engages the pinion 79 that is fixed tothe shaft 80, thus rotating the rollers 74 and 74'. It Will be seen thatby increasing or diminishing the number of cogs, 81, that are to beplaced in the socket 7 8 of the gear 78, a greater or lesser quantity ofsolder may be fed with each revolution of the machine. The amount ofsolder fed should be regulated by the size of the can bodies being made.At the time the solder is fed as just described, the mutilated-gear 68engages the pinion 67 that is fixed upon the shaft 66, thus rotating thecrank-wheels and 69 and carrying forward, through the links and 70,slotted rocking-bars 62 and 62, lateral sliding bars 63 and thevertically adjustable support 63, and the soldering iron 56. The end ofthe solder, 71, as it is fed up comes immediately in front of the lappededges of the sheet of tin A, and opposite the groove through the bottomof the open split cylinder 30. As the heated soldering iron 56 is thrustforward as described, it travels over the solder wire as it is fed up,thus melting the solder and spreading it along the seam of the foldedsheet of tin A. The soldering iron 56 is carried through the open splitcylinder to its extreme end and back again beyond the front limit of thecylinder. In other words,the soldering iron 56 is reciprocated throughthe open split cylinder 30 and outsideof said cylinder at its front end.Upon its return to its position of rest, the soldering iron 56, byreason of the mutilation of the gear 68, is allowed to remain at restuntil a second sheet of tin shall have been fed into the machine, formedand clamped, as already described. Immediately upon the withdrawal ofthe soldering iron 56 from the open split cylinder 30, the rotation ofthe mutilated gear 40 releases the pressure of the T-end 34 of thevertical reciprocating-rod 34 and releases the segmental clamps 45 and45, from the tin operated upon and the cylinder 30. Immediately as thesegmental clamps 45 and 45' are released from and partially forced offthe split cylinder, while another sheet of tin A, is being pushed oversaid split cylinder ready to be operated noon.

The description of the operation of the ma chine now given describes onecompleted revolution of the machine. It will be seen how successivelythe stock-feed mechanism, then the forming and clamping mechanism, andthen the soldering mechanism, come into action, and how the combinedaction of the three mechanisms completes the process of seaming a singlecan body; and that a single can body is seamed with each completerevolution of the machine. It will further be noted that as the feedmechanism carries a sheet of tin A over the split cylinder 30, the feedmechanism has a slight rest, during which slight rest the vertical bar34 is depressed so as to grip the sheet of tin between the T-end 34' ofthe vertical bar 34 and the open split cylinder; and that while thesheet of tin is so gripped, the stock-feed mechanism is withdrawn so asto be clear of the cylinder before the segmental clamps 45 and 45areclosed upon the split cylinder with the sheet of tin between. And itwill be observed that the segmental clamps remain closed upon the splitcylinder to hold the formed tin firmly while the solder is being fed andwhile the soldering iron makes its travel through the split cylinder andback again; and that while the segmental clamps are closed upon thesplit cylinder, and while the soldering iron is in operation, thestock-feed mechanism is at rest. And it will be seen that the stock-feedmechanism again operates immediately upon the return of the solderingmechanism to its position of rest and upon the release of the segmentalclamps.

It will be seen that the soldering iron is kept hot by means of gaswhich is carried to the chamber within the iron through the flexible gastubing 60 and through the pipe 59 that enters the chamber of thesoldering iron. In practice, the burning gas comes from the inner end ofthe pipe 69 and is deflected by the back Wall of the iron down. andaround the walls of the chamber, and the escaping gases come out throughthe air passages 58.

By having the open split cylinder 30 removably attached to that portionof the main frame 1', 1, by means of bolts passing through the flange31, and by making the segmental clamps 45 and 45 interchangeable, themachine may be used for seaming cans of vari- 1 cos sizes by having avariety of sizes of split cylinders and segmental clamps.
